[PATCH v1 0/2] isa: Make the remove callback for isa drivers return void

Hello,

as described in the commit log of the 2nd patch returning an error code
from a bus' remove callback doesn't make any difference as the driver
core ignores it and still considers the device removed.

So change the remove callback to return void to not give driver authors
an incentive to believe they could return an error.

There is only a single isa driver in the tree (assuming I didn't miss
any) that has a remove callback that can return a non zero return code.
This is "fixed" in the first patch, to make the second patch more
obviously correct.

Best regards
Uwe
